DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the setting of a code filter used in a communication device, particularly in a character mail service of a portable telephone, for preventing mischievous mails and erroneous mails.

[0002]

2. Description of the Related Art Heretofore, text mail services such as so-called sky mail and petit mail have been used in portable telephones. In this text mail service, mail is transmitted by inputting (setting) text information and a telephone number of a receiving party, and then operating a transmission key.

[0003] In such a character mail service, character mail can be easily transmitted only by knowing the telephone number of the other party as described above. Text mail may be received.

In order to solve such a problem, a PIN (Personal Identity Number) code filter setting (hereinafter, PIN setting) is conventionally known. The PIN setting is like a personal identification number. If the sender (recipient) has the PIN setting turned on, the sender can send an e-mail unless the sender knows the recipient's PIN. Can not. If the sender knows the recipient's PIN, this PI
N is added as data and mail is transmitted.

[0005] By setting the PIN of the user's mobile phone to ON, character mail from a sender who does not know the PIN is not received, and incorrect mail can be prevented.

[0006]

However, in the above-mentioned portable telephone, when the sender A sends an e-mail to the receiver B with the PIN setting ON and the receiver B replies, the receiver B sends the sender B a caller. It is necessary to teach the PIN of A in advance, which is very troublesome.

In such a case, even if the receiver B does not want to give the PIN to the sender A, if the receiver B receives a reply, the receiver B must know the PIN. .

Accordingly, an object of the present invention is to provide a communication terminal device capable of obtaining a reply without transmitting its personal identification code to a recipient when transmitting a text message (mail).

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a character mail is sent to a partner communication terminal.
When transmitting the password, the personal communication code is transmitted to the communication terminal of the other party in addition to the character mail, and the character message transmitted from the communication terminal of the other party and the password of the other party are received. When replying to the communication terminal of the partner, the personal identification code of the partner is automatically added to the reply character mail and transmitted.

Thus, even if the responder does not know the password of the other party, the responder automatically inserts the transmitted sender's password in the reply mail. You can still reply. As a result, the sender can get a reply without giving his / her personal identification code to the receiver (replyer).

According to a first aspect of the present invention, as in the second aspect of the present invention, the data format of the character mail includes a code storage area in which the password of the other party is stored, and a mail content. In the case of transmitting a character mail to the communication terminal of the other party, the mail information storage area is placed in a predetermined storage area position of the mail information storage area,
When replying to the partner communication terminal, the transmitted secret code of the partner may be stored in the code storage area.

The storage unit 13 stores a control program related to communication (call and mail transmission / reception), and also stores various data such as character message data and an address book in which names and telephone numbers are registered. Has become.

Thus, a normal telephone (call) function is realized, and a telephone number (communication address) is transmitted to a communication partner terminal as a text message service, so-called skywalker, petit mail, short mail. , And a function of transmitting and receiving text mail such as A mail. The text message transmission / reception function is such that the user operates the key operation unit 4 to create a text message and transmits the data to another mobile phone 1;
The function is to receive a text message from another mobile phone 1, store the data in the storage unit 13, search freely and display it on the display unit 3.

The mobile phone according to the present embodiment is
The user can freely set his / her personal identification code (the above-mentioned PIN), so that only a character mail in which his / her personal identification code is set can be received. For example, PIN is 4
It is registered with a digit number.

Next, transmission / reception of character mail which is a main part of the present invention will be described. FIG. 3 is a conceptual diagram showing the concept of character mail transmission and reception, and shows the format of mail data.

The following description is based on the mobile phone MS.
1 (hereinafter referred to as MS1) and the exchange of e-mails with the mobile phone MS2 of the communication partner, both of which are PIN setting ON and the security codes PIN1 and PIN2 are respectively set, and the user of MS1 knows PIN2. Yes, MS2
It is assumed that the user does not know PIN1 (FIG. 3).

First, a mail format will be described. In this example, a text message service provided by a mobile phone service provider is a question-response format mail service independently adopted by the applicant according to the sky mail format. It is. In other words, the playability is further enhanced in accordance with Skymail (this is hereinafter referred to as question response mail).

First, as shown in FIG. 3, the basic format of the Sky Mail has a data storage area 20 at the beginning of which the telephone number of the communication partner is entered, and a code storage area in which the PIN of the other party is entered. 21. The portion other than the data storage area 20 is a message storage area 22 in which message contents (transmission and reception contents) are stored.

In the question response mail, the message storage area 22 is further divided into an information storage area 23, a question storage area 24, and an answer storage area 25. As the name suggests, the question storage area 24 is for storing the contents of a question mail, and the answer storage area 25 is for storing an answer to a question.

In this example, a plurality of question items and the like are stored in the storage unit 13 in advance as fixed phrases in addition to free words to be freely entered. The corresponding item number is stored. When this question item is selected by the mail creator, the item number corresponding to this is stored in the information storage area 2.

Can be put in. Further, the user's personal identification code PIN1 is put in a predetermined storage area position at the beginning of the answer storage area 25. In other words, when the question mail is newly transmitted, the answer storage area is empty, so that the PI
Entering N1 has no problem.

If the question is a fixed sentence, the item number is put in the storage area 23. If the question is a free word, the item number 0 is put in the storage area 23 and the question storage is performed. In the area 24, the content of the question of the requester is entered. As described above, in this example, when transmitting an e-mail to MS2, which is the other party's communication terminal, PIN1 which is its own personal identification code is transmitted to MS2 in addition to the text mail.

Then, such a question mail and MS
When the MS2 receives the PIN1 of 1 and sends a reply by operating a predetermined key, the following processing is performed.
PIN1 in the response storage area 25 transmitted from the MS1
Is automatically copied to the code storage area 21 in the own reply mail format. When the answer according to the content of the question is freely answered, the answer is stored in the answer storage area 25. Although not shown, the answer, the fixed phrase and the corresponding item number are also stored in the multiple storage unit 13. When the fixed phrase is selected and input, the item number corresponding to the storage area 23 is entered and the MS1 is entered. Sent to. When replying to the communication terminal of the other party in this way, the password of the other party is automatically added to the reply character mail and transmitted.

By doing so, the MS2 user can use M
Even if the MS1 does not know the PIN1 of S1, the MS2 copies the PIN1 sent in the process of the control circuit 9 and automatically puts it into the code storage area 21 in the reply mail format. You can reply even if it is set. As a result, MS1 can get a reply from MS2 without telling the receiver his / her personal identification code. In FIG. 3B, the PIN 2 is shown in the answer storage area 25. However, this may be deleted at the time of reply, and the answer storage area 25 may be increased.
